Abstract: In this study, a single-phase body-centered-cubic (BCC) high-Cr FeCrNi multi-principal element alloy with excellent ductility was investigated. The remarkable deformability was primarily attributed to crystal rotation, twinning, and stress-induced ω phase transformation. The interaction of the three deformation mechanisms endowed the alloy with outstanding work hardening capability. • A high-Cr alloy with single BCC phase possesses exceptional ductility. • Crystal rotation, twinning, and stress-induced martensitic transformation are activated during deformation. • The "dynamic refinement" effect drives high work hardening rate.
